erably of copper, and which extend around the dial post 13. To preventshort circuitm of these brushes by the metallic finger dial 13 a disk ofinsulating material 14 is interposed therebetween, and purpose aninsulating ring 12 is placed between the brushes themselves. From Figure2 of the drawing it will be seen, the telephone to which the inventionis attached is equipped with a number dial 15 of insulatin material;however, should it be desired to attach the device to a a metallicnumber dial, it would only be necessary to place another disk, similarto the disk 14, below the brushes l and 11. Electric bulbs 11 extendthrough apertures in brush 1(), through insulating ring 12, beneath thebrush, and contact with brush 11. on post 13. It will be readily seenthat the current must pass through both connecting wires a--a, beforethe bulbs will be lighted.

The transmitter 3 is shown, and below it the receiver hook 4, supportingthe receiver 5, as the receiver is lifted from the hook, the operationshown in Figure 3 takes place, namely the contact point on the receiverhook 4, allows spring contact 6 to move forward, and contact with member7, thereby making a circuit through wires arr-a and the battery 8. Asthis circuit is made, it sends a current through wires ara, to brushes11 and 11, and through them to light bulbs 10. 15 represents theporcelain lettered dial plate.

It should be understood that a suitable This invention relates totelephone equipment, and refers to an illuminating means in attachmentto telephones of the automatic type, whereby the numbers on the dial maybe rendered visible when the receiver is removed from the hook.

An object of the invention is the provision of an electric light orlights mounted on the dial post and connected by suitable wiring to thereceiver hook wiring, so that when the hook is lifted, the circuit tothe lights will be made, and same will illuminate the dial, and when thereceiver is hung up the lights will be extinguished.

Another object is to provide a device of this character that may beattached readily and quickly to an automatic telephone, and whoseoperation and construction is simple and durable.

Another object is the provision of a suitable switch adapted to cut oifthe current to the lights when it is not desired to use same.

Other objects and features will be set forth in the followingdescription, taken in connection with the drawings attached hereto, asfollows:

Figure 1 shows a side elevation of an automatic telephone, with theilluminating device in attachment thereto.

Figure 2 represents a cross-section of the dial, showing theconstruction of the illuminating dial on the dial post.

Figure 3 shows a detail sectional view of 35 the receiver hook, showingthe contact made when same is lifted.

Figure 4 shows a side elevation of an automatic telephone with theinvention attached, the dial and the elements of the invention incross-section, and part of the telephone broken away to show the mannerof wiring to the lights on the dial post.-

Figure 5 shows a top view of the dial with the invention attached, partbeing broken away to show the vdetail of construction of the invention.

Following Figures 1 and 4, the telephone 1, of ordinary construction,rests on base 2, porcelain dial post 13 with metal finger dial .13fastened thereon by means 9 an a the current the bulbs, when oint onwires aa, whereby may be switched ofi from it is desired to do so.

It should also be method of construction shown as it involves lesschanging telephone structure, and the additional structure.
